Story
Meet Henry Lee — Our Big-Hearted Dude Searching for a Softer Life Henry Lee is a 6–8-year-old, 100-pound gentle giant with the personality of a classic Rottweiler — loyal, devoted, and full of quiet charm. He'll need to be reminded he's a senior as he has tons of energy and is always on the go. What Henry Lee Needs • A foster OR adopter who understands the Rottie breed • An adult-only home (no kids due to his size + lack of history) • No other pets What Henry Lee LOVES • Being outside in the yard • Car rides • Squeaky toys and balls • Soaking up ALL the attention • A good nap in his crate (toss a treat in and he'll happily go right in!) This sweet senior deserves a peaceful home where he can enjoy his golden years with comfort, love, and dignity.January 10, 2026, 2:16 pm
